"The Westbury Monthly Meeting of Friends records the death of John Hallock, grandson of Peter of 1640, and that of his wife Abigail Swazey, at Setauket, in Brookhaven, in 1737, "both very ancient and in unity with Friends." She died Jan. 23, 1737. Deeds at Riverhead name four of his sons, John 2d, Peter, Benjamin, and William, who all settled near him in Setauket, as did also his son Jonathan, whose children and William's are known to have been cousins. A deed in 1715 from William to his son William is now held by their descendant, Edmund P Hallock. The neat dwelling of John Hallock 1st, covered with cedar, and that of John 2d still remains (1863) in Setauket."
